Just a couple thoughts, does she fall asleep on her own? DD1 was not at that age and had bad naps like that tho we switched to one nap a bit later at 14 mths. DD1 eventually was able to fall asleep on her own by 15/16 mths and we still had 70-80 min naps till after 19 mths. She would often do a 13 hr night tho and I always had her in bed by 6:30ish and she was up by 7/7:30 am. To me, that A time seems a bit long but all kids are different. Both my girls never liked a long prenap A time. DD1 was at 4.5 hrs for a long time and maybe around age 2 was at 5/5.5 hrs.
DD2 is a much better sleeper (likely due to earlier sleep training) and didn't switch to one nap till 18 mths when I made her cause the summertime came, she is still only at 5 hrs A time and would do less if I let her. We are often out with activities for DD1 so she doesn't get to nap till 1 pm and that is with an 8 am wakeup. So maybe try a shorter A, maybe just ride it out. As my first child has shown, not all do those 2 hr naps. She did do much better after 19 mth tho and actually still naps at almost 4.5 yrs so all is not lost! HTH!
